Expansion Storage Shelves connect to the Primary Shelf and to other Expansion
shelves with two SAS-3 cables.
The Primary Shelf has a single SAS-3 port on the left side of each RAID controller
I/O module. This port connects to SAS-3 port A in the Expansion I/O modules.
To connect a compute node to a Primary Shelf
1
Obtain four SAS-3 cables for each compute node.
2
Identify the SAS-3 ports in slot 3 and slot 7 of the compute node that is closest
to the Primary Shelf.
The ports in each slot are labeled 3, 2, 1, and 0 from left to right.
